Default Overheating / Wifi Issues - 01-26-2009, 09:29 PM

I'm having a problem with my Dell Mini 9 overheating.

After about an hour of constant use the bottom of the Mini 9 gets pretty hot. It then loses wifi connection.
If I reboot the computer, wifi will work again for a few minutes before losing connection.
When it loses the wifi connection in XP, I look in device manager and "Broadcom 802.11g Network Adapter" is missing.

Everything was working perfectly for the first 2 weeks.
The only upgrades I have done is installing OS X and 2GB of ram. (Been waiting 3 weeks for my Runcore 64gb to arrive.)

Tried the following with no success:
1. Reseated Wifi Card
2. Put back in the original 1GB stick of ram.
3. Reinstalled OS X 2 times to see if it was a software issue.
4. I then restored from backup the Windows XP image that came with the computer.

I contacted dell tech support and they suggested upgrading the bios from A03 to A04.

I can reproduce this problem over and over again. In XP I'm using Hardware Monitor and it is showing an ACPI temp of 72C and Core Temp of 70C.

Is 70-72 degrees Celsius nomal?
Would the bios upgrade help?
Should I try upgrading to an N card?
Send it in to dell for repair?

Thanks,

Your temps are about double what is normal. I wonder if the thermal pads on the bottom of the metal panel under the keyboard (palmrest) are not touching the chips.

I forgot to mention that the 70-72C temp is not at idle.
It gets that hot after 100% CPU utilization for half an hour.

I lifted up the keyboard and put some pressure on the spots that should have contact with the CPU and other chips.
It feels like there is a solid contact.

Dell is sending a box for me to ship it into their service Depot.

I'm keeping my fingers crossed. I hope they replace the motherboard with one that has wwan slot.

Out of curiosity what are you doing that you are sitting at 100% cpu for a half hour?

Also I'm reserving my judgment but I think Dell will be replacing some pieces for you.

Also if you include a cute little note with smilies on it asking for a M/B with the little extra you asked for you might get it. I do RMAs and redeployment for a computer company and a simple note asking politely for a favor usually gets that favor if I can swing it.

That note is a really good idea. Too bad I have already shipped it out.

I normally use the Mini 9 to watch videos, check email, web browsing. Under regular use in both OS X and Win XP it overheats in 30-60 min.

For testing purposes and to replicate the problem consistently I was using Prime95 under WinXP to keep the cpu at 100%.

Oh man! I wish you had read the thread "When Is Hot Is Too Hot?" Turns out, HWMonitor reports incorrectly. :!: http://heh.pl/&3hT Go to page 6 and read post by KwisatzHaderach.

I feel your pain. See my post here: http://heh.pl/&3hS I'm now running on battery and right after booting I was at 47C. I've been browsing for about 15 minutes, have my mini straddling two book to allow air underneath and I'm sitting at 55C-57C and ambient is 69F.

Yes but his wifi was dying too. I think his bad juju demons are a little more, tangible, than the demons of some alarmist users on this forum.

Great News!

I recieved my laptop from the dell service depot.

They replaced my Motherboard and it now has a WWan slot

I still need to stress test the Mini9 to see if it has Wifi issues when it gets hot.

I already use WMwifiRouter with my Sprint Phone for Wireless Internet Access.
So I'm not sure what to do with the free WWan slot.

Any Suggestions?

I am too green with envy to be able to offer ideas.
